Abstract Nowadays global engine construction gets significant progress at a technological level, but specified manufacturers do not release any information about the composition, the structure of the algorithms and the software used by their equipment. It is possible to obtain information only fragmentary and, for example, the description of the electronic control unit algorithm is completely missing. This is a barrier for small companies to improve and adjust existing engines for specific purposes. The present paper describes and develops algorithm synthesis for an electronic diesel engine regulator. Mathe-matical modelling of the automatic control system has been carried out within the framework of the research. The results of the research have demonstrated the efficiency and sustainability of automatic electronic control system using the proposed algorithm.

In this paper, the semi-physical simulation technology is introduced with the design and implementation of a semi-physical simulation test bench. A certain low-speed marine diesel engine of high pressure common rail (HPCR) electronic control system is taken as the subject of the test bench. In order to retain the functional and structural features of the HPCR electronic control system, the essential components are in consistent with the target engine, and some auxiliary parts are simplified and reformed. Specially, a real-time simulation model is built based on the principles of Mean Value Engine Model and cylinder moving method, which captures the requirements of ECU, such as the crank angle, the exhaust valve stroke signal, the scavenging pressure and so on. Therefore a closed-loop control system is accomplished including a real-time controller deployed in the simulation model, ECU and the executing agency of HPCR system. Additionally a monitoring management system is developed for the test bench with the functions of acquiring signals, monitoring parameters, storing data, alarming and etc. Finally, some tests are finished in the test bench and through analyzing the experimental results, the test bench can perform the characteristics and functions of the HPCR electronic control system. The semi-physical simulation technology can be used for the functional verification and performance test of HPCR electronic control system for the low-speed marine diesel engine.

The Impact

A method of fuel injection rate shaping of the Diesel engine common rail fuel system with common rail injectors and solenoid control is proposed. The method envisages the impact on control current of impulses applied to the control solenoid valve of the common rail injectors for variation of the injection rate shape. At that, the fuel is supplied via two groups of injection holes. The entering edges of the first group with the coefficient of flow, ??B, were located in the sack volume and the entering edges of the second group (coefficient of flow, ??H) - on the locking taper surface of the nozzle body. The coefficients of flow, ??B, and ??H differ considerably and depend on the valve needle position. This enables to adjust the injection quantity by injection holes taking into account operating conditions of the Diesel engine and hence - by the combustion chamber zones. Using the constant fuel flow set-up, characteristic of the effective cross-section of the common rail fuel system injector holes was investigated. The diameter of injector holes was 0.12 ? 0.135 mm. The excessive pressure at the entering edges varied from 30 to 150 MPa and more and the excessive pressure in the volume behind the output edge - from 0 to 16 MPa.
